Title: Regeneration of cellulose products
IPC: D21C11/06
Filed: 1969-10-16
Abstract: Acid magnesium bisulphite liquor is regenerated, after the separation of the cellulose material produced, by concentrating and burning the spent liquor in a furnace; separating MgO particles from the effluent gases; preparing an aqueous suspension of the MgO particles; and contacting the suspension with effluent gases to form an acid solution containing magnesium bisulphite and magnesium sulphite, having a temp. of about 65 degrees C. The process is improved by contacting the acid solution with SO2-containing gases from a sulphur burner to convert practically all the magnesium sulphite into magnesium bisulphite and, after the removal of the precipitated impurities such as CaSO4 and MgSO4, contacting the solution again with SO2-rich gases at about 27 degrees C to produce a solution of Mg(HSO3)2 having a high content of free SO2.

Title: Monitoring neutron source - in borehole tool used for uranium detection
IPC: G01V5/10
Filed: 1972-06-16
Abstract: A borehole tool includes a pulsed neutron source which irradiates a rock formation with bursts of fast neutrons. Radiation produced is measured by a detector, and a second detector monitors the output from the neutron source. A conventional detector is too slow to measure the neutron burst directly, so a known target is irradiated and the delayed radiation from the target is monitored to provide an indirect measure of the source output.

Title: Electrode press - mobile shear-head gives clean parted-off faces
IPC: B23D25/04
Filed: 1972-12-22
Abstract: Press-formed electrodes are parted off during ejection from the press, the operation being made fully automatic the cutting-off head advanced by a hydraulic cylinder at the same speed as the speed of electrode ejection from the press at the moment when shearing takes place, thus there is no deformation of the parted-off edges because there is no drag of shear-blades during the cut-off operation. The cylinder which advances the mobile cutting head can be actuated simultaneously with the shearing action as the electrode advances through the beam of a photo-electric relay.

Patent FR-2278767-A1 (FR)
Title: Multi-stage extn of sugar from cane bagasse - by repeated washings in progressively weaker juices with deaeration in each stage
Inventor: PITHOIS PHILIPPE
IPC: C13B10/02
Filed: 1974-04-11
Abstract: In each stage bagasse is stirred into suspension in a washing juice, the suspension deaerated and then pumped in turbulent flow through pipework leading to a separator, e.g. a screen, where enriched juice is sepd. from the bagasse; this whole process is repeated several times, the washing juice being circulated counter-current to the bagasse so that as bagasse progressively loses its sugar it is put into suspension in the next stage with correspondingly weaker washing juice each time. Pref. part of the juice sepd. from bagasse in one stage is recycled in the suspension of the same stage. The multi-stage, counter-current extraction improves mass transfer and gives a higher yield of product. Deaeration suppresses capillary retention of juice in the bagasse.

Title: Rejection device for floating organic matter - from purified effluents by aeration tank with special shaped base
IPC: C02F1/00
Filed: 1974-06-05
Abstract: Floating matter is rejected from purified effluents in an aeration tank in which the base is turned up in a semiparabolic, semi hyperbolic or semitoroidal form. The tank comprises a cylindrical envelope with a base with its upturned portion. The top of the tank has a horizontal ring, the smaller dia. of which forms the internal edge of the tank. The nozzles on the ring allow of the evacuation of the floating matter from the clarifier to the aeration tank while the outlet tube is provided for withdrawing the purified effluent from a level below the min. for the station. A floating platform, in the form of a torus, supports the aerator and acts as a screen against eddy currents, produced by the aerator, and prevents any communication between the top of the tank and the clarifier. The floating organic matter which has been entrained by the hydraulic movement produced by the aerator is held back in the upper part of the tank by the floating plate. The device can be used in biological purificn. stations of the single block type.

Title: Conductor insulation coating appts. - uses conductor heating by current flow in cct. closed by conductor passage between respective contacts
IPC: H05B3/00
Filed: 1975-01-22
Abstract: The conductor coating apparatus is intended for providing the conductor with appropriate insulation and has at least one path with a coating station for the conductor. An electric circuit is provided with a pair of contacts along this parth upstream with regard to the coating station.

Title: Loom has cloth feed roller which is reversed after stoppage - and automatically stopped ready for re-commencement of weaving
IPC: D03D49/20
Filed: 1975-05-21
Abstract: Cloth woven on a loom is advanced by a cloth feed beam driven by a drive device located pref. at one end of the beam. Pref. at the other end of the beam is provided a transmission, whereby rotation of the beam is transmitted to a drive friction pad which acts on actuating friction pad to maintain a switch open. When the loom is stopped the direction of the cloth feed beam is reversed to allow the operator to correct a fault in the cloth. When the direction of the cloth feed beam is reversed the drive friction pad, also rotates in the opposite direction and allows the actuating friction pad to close the switch and so stop the cloth feed beam from rotating and posn. it for recommencement of weaving. The period of time during which the cloth feed beam is reversed in automatically controlled so that after a stoppage the loom is correctly set up for a re-start.
